原因：
atomikos的默认配置中 transactions.properties中：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 | # SAMPLE PROPERTIES FILE FOR THE TRANSACTION SERVICE # THIS FILE ILLUSTRATES THE DIFFERENT SETTINGS FOR THE TRANSACTION MANAGER # UNCOMMENT THE ASSIGNMENTS TO OVERRIDE DEFAULT VALUES; # Required: factory implementation class of the transaction core. # NOTE: there is no default for this , so it MUST be specified! # com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory # Set base name of file where messages are output # (also known as the 'console file' ). # # com.atomikos.icatch.console_file_name = tm.out # Size limit (in bytes) for the console file; # negative means unlimited. # # com.atomikos.icatch.console_file_limit=- 1 # For size-limited console files, this option # specifies a number of rotating files to # maintain. # # com.atomikos.icatch.console_file_count= 1 # Set the number of log writes between checkpoints # # com.atomikos.icatch.checkpoint_interval= 500 # Set output directory where console file and other files are to be put # make sure this directory exists! # # com.atomikos.icatch.output_dir = ./ # Set directory of log files; make sure this directory exists! # # com.atomikos.icatch.log_base_dir = ./ # Set base name of log file # this name will be used as the first part of # the system-generated log file name # # com.atomikos.icatch.log_base_name = tmlog # Set the max number of active local transactions # or - 1 for unlimited. # # com.atomikos.icatch.max_actives = 50 （原因） # Set the default timeout (in milliseconds) for local transactions # # com.atomikos.icatch.default_jta_timeout = 10000 # Set the max timeout (in milliseconds) for local transactions # # com.atomikos.icatch.max_timeout = 300000 # The globally unique name of this transaction manager process # override this value with a globally unique name # # com.atomikos.icatch.tm_unique_name = tm # Do we want to use parallel subtransactions?

修改默认配置中的：
| 1 | com.atomikos.icatch.max_actives = 50 ------改为更大就可以解决 |
